SEALING noon' PACKAGES.

To all 'whom t may concern.'

Be it known that l, FRANK GRAEBER, a citizen of the United States,residing at Norristown, in the county of Montgomery and State ofPennsylvania, have invented new and useful lmprovements in Sealing FoodPackages, of which the following isa specication.

My invention relates to packaging food products and more particularly tothe providing of packages of this typewith a paraffin coating, thepresent application being drawn to the apparatus employed inproducing'the packaged article.

rllhe packaged article itself and the method of producing the same,hereinafter set forth, are not claimed in this application as they formthe subject matter of a divisional application S. No. 795,104, filedOctober 14, 1913, in response to the requirement of the United StatesPatent Office.

In packaging food products, such as jellies, etc., the container isvgenerally in the form of a glass tumbler, and after the jelly is placedtherein, a' coating of paraffin is applied to the exposed surface ofthejelly. This coating has generally been in the form of a relatively fiatlayer of paraflin of substantially equal thickness throughout thecoating, the result being that either a relatively thick layer must beemployed in order to provide the periphery of the coating with a surfaceof sufficient extent to providefthe proper adhesion to the glass, orwhere the layer has been comparatively thin, such peripheral contact hasbeen insufficient to provide the proper excluding qualities as well asadhesion to the glass.

The present invention contemplates the forming of a comparatively thin`layer with aperipheral surface adapted to contact with the glass, saidcontacting surface being of greater length lengthwise of the glass thanthe thickness of the layer, this being provided by displacing theparaffin while in its liquid state so as to decrease the thickness ofthe initial layer, the displaced material being` forced along the glasssurface so as to cause it to extend above the top plane of the mainportion of the layer, providing the appearance somewhat of a dish shapedcoating, the lower surface of the layer, however, extending throughoutthe Specification of Letters Patent.

area of the exposed face ofthe jelly, the result being that withoutincreasing the amount of paraifinrequired, a coating of l sufficientthickness forthe desired purpose is provided, and at the same time amaxi-y mum peripheral surface in contact ywith the ing such package, andthe provision of apparatus which will form one way in which' this methodmay be employed.

Further objects are to provide an apparatus which is capable ofproviding-the paraffin coating to a multiplicity of containerssimultaneously, the apparatus being i simple and eihcient 1n operation,durable in construction and which can be manufactured and operated at arelatively low cost.

To these and other ends, the nature of which will be readily understoodas the iiivention is hereinafter disclosed, my invention consists in theimproved package, the method by means of which such package may beprovided, and the improved construction and combination of partsembodying the apparatus adapted to form a way in which the method may beemployed, all as hereinafter fully described, illustrated in theaccompanying drawings, and more particularly pointed out in. theappended claims.

In the accompanying drawings in which similar referencecharactersindicate similar parts in each of the views, Figure l is aview partly in sectionand partly in end elevation of a machine adaptedto carry out the embodiment of my invention. Fig. .2 is a sectionalview. taken on the line 2 2 of Fig. l. Figs. 3 and 4 are verticalsections of the valve structures, these views showing differ-4 entpositions of the valves.: Fig. 5 is a horizontal sectional view of oneof the valve containing cups. Fig. 6 is a detail plan view of acoil'structure adapted to heat the paraffin. mechanism for manipulatingthe valve operating mechanism. Fig. 8 is a detail view of the clutchmechanism. i Figs. 9 to 12, inclusive, are views, somewhat diagrammatic,illustrating the method in which the coating Fig.x7'is a detail view ofthe is produced bythe apparatus herein disclosed. Figs. 13. 14 and 15are detail views of the carrier for the containers. Fig. 16 is a detailview showing a simple way in which my method may be carried out.l

The package with its paraffin coating formed in accordance with mypresent inV vention is shown, somewhat diagrammati cally, at the bottomof Fig. 12, the glass or container being indicated at 25, the foodproducts at 26, and the coating at 27, the coating being shown as in theform ofy a comparatively thin layer with a flange 27a projecting`upwardly peripherally of the layer and in contact with the inner faceof the glass, thus making an extended peripheral contact with the glass,and at the same time providing a relatively thin layer of sufiicientthickness, however, to provide the desired excluding qualities. It is tobe understood, however, that the present invention is not limited toathin layer, nor to the amount of projection of the flange 27a to providethe peripheral contact, these necessarily varying according to theparticular food products being packagedV as well as to meet the desiresof the user,the main feature being that the-thickness of the layer beincreased peripherally at its point of contact with the glass andlengthwise of the glass, it being preferred that the increasevbe on theside of the layer opposite that of the food products. rIhe method bywhich this result is obtained is shown diagrammatically in Figs. 9 to12, consisting in forming a layer rof liquid paraffin on the top of thefood products within the glass, preferably in measured quantity, andthen placing a suitable plunger of less diameter' than the diameter ofthe glass on, the top surface of this layer, whilestill in liquid state,and applying pressure to the plunger, thereby forcing out air bubblesetc., which may be exposed on the top of the food products and at thesame time displacing a portion o-f the paraffin so that it will passbetween the sides of the plunger and the glass, the plunger beingretained in position suliciently long to permit the paraffin to set,after which the plunger is withdrawn. A simple forni for producing thisresult is shown in Fig. 16, in which the plunger is indicated at 28. Asa result, the layer is expanded along its periphery and provides a,relatively wide surface contact with the glass and thus produces `amaximum excluding effect. i

In order, however, that this packaging may be employed commercially toprovide a maximum output, I preferably employ apparatus for carrying themethod into effect, oneform of. such apparatus beine shown in thedrawings, in which 30 designates a supporting frame having a bed 31 onwhich is mounted a tank 32, the bottom of which is preferably spacedfrom the top of the bed as by pillars 33.

The tank is preferably of asize to contain a considerable quantity ofparaiiin, and for the purpose of maintaining it in a liquid state, Ipreferably employ a heating coil 34: suitably arranged for the purposeof maintaining the paraffin liquid, one way in which this may beprovided being shown in Figs.

2 and 6, in which the coil is shown as extending from a point adjacentthe top of the tank to a point adjacent the bottom thereof, suitablecross connections being einployed for the purpose. of increasing theheating effect. The coil is adapted to be connectedfto a suitable sourceof supply, either steam or hot water, and is of a form which will insurethat the paraffin in the tank be maintained in liquid state, andespecially that portion adjacent the bottom of the tank. If desired, adrainage cock 35, may be employed for clearing the tank.

rlhe apjniratusherein disclosed is adapted to apply the coating to aplurality of containers, the disclosure of the drawings showing astructure adapted to simultaneously operate on 'two dozen containers.These containers are adapted to be placed in a predetermined position ona vertically movable carrier so as to locate them below a correspondingnumber of valve structures carried by the bottom of the tank. its thesestructures are substantially similar, but one of them will be described.

designates a cup-shaped receptacle which is secured within the bottom ofthe tank, preferably projecting above and below the planes of suchbottom, it being essential that it, project below, but, if desired, itmay not project above, although this latter' is preferred in order thatsediment, etc., which may be contained within the paraffin will not havea tendency to drain int'o the cup. T he bottom of the cup is providedwith one or more openings 86 (I prefer to employ two openings), theseopenings being spaced apart and forming the discharge openings for theparaffin.

37 designates a valve member which is carried by a stem 38, the latterbeing suitably mounted for rotation or oscillation, said stem extendingthrough a cut-off plate 39 mounted within the cup above the valve andpreferably held against rotation by suitable means such as a spline 39a.I preferably render the plate 39 yieldable slightly, and for thispurpose I may employ rods 39h carrying a collar 39 between which and abar 40 hereinafter referred to, is mounted a spring 39d; I preferablyemploy two of these structures approximately diametrically opposed withrespect to the plate. The plate 39 is preferably provided with one ormore openings 39e `(the number corresponding to the number of openings'36a), the openings 89e being positioned out of vertical alinement withthe openings 36a, a

4preferable arrangement being shown in Fig.

5, in which the openings 86a are shown in dotted lines. rIhe valve 37isalso provided with a similar number of openings 87a and in theoperation of the apparatus, the valve is positioned to have its openings87a in alinement with the openings 89e when the apparatus is at rest,the valve in this position, being adapted to receive the paraffin, thelatter filling the openings 37a as Well as the openings 39e.

As will be readily understood, a movement of the valve in a rotarydirection will carry its openings out of alinement with the openings 89eand into alinement with the openings 86a, the movements yof the valvebetween these positions providing for the segregating of the properamount of paraffin for use in providing the coating'for a singlecontainer, the valve receiving the paraiiin through the openings 39e anddischarging it through the openings 36a. As will be understood, theImovement of the valve in passing from itsreceiving to its ydischargingposition will act to cut o the supply when the openings 37a have passedout of alinement with the openings 39e.

As will be obvious, the size of the openings 37'3, will determine theamount o-f paraftin discharged, the normal amount being about aspoonful. The cups 36 are preferably arranged in rows, and each stem 38is provided with la pinion 41. rIhe pinions 41 are operatively connectedto a plurality of racks 42, each rack preferably operating the pinionsof two rows of cups, the racks each being located between the rows andhaving teeth on its edges. For the purpose of operating the racks, Iemploy suitable pinions 43 mounted on a shaft 44 above the racks, thelatter having teethon their upper faces adapted to engage with thepinions 48. The shaft is adapted to be oscillated by means of a crank 45having one end carried by the shaft and having its other end connectedto a connecting rod 46, the opposite end of which is adapted to bemounted to be actuated by one or more cams 47 carried by the drive shaft48. As the complete cycle of movements of the valves must take placeduring but a portion Lof the revolution of the drive shaft, for apurpose hereinafter rreferred to, I preferably employ two cams 47 soarranged as to provideffor positive movements of the valves in bothdirections and at proper time intervals. A preferable form of camarrangement is shown in Figs. 2 and 7. Y

v The drive shaft 48 is driven from a suitable source of power,thedrawings illustrat- `ments of the shaft 48 to one completerevolution, the successive revolutions of this shaft beingat the will ofthe operator. For this purpose, I operatively connect the fast pulley toa gear 50 loose on vthe shaft 48,

and provide a friction clutch structure which is adapted to be operatedkat will and which will automatically cause a disengagement when acomplete revolution of the' shaft 48 is had. One way in which thisresult can be produced is shown in Figs. 1, 2 and 8, in which 51 and 52designate the opposing members of a clutch mechanism, the

dinally of the shaft 48 to rotate therewith, the movement of the member51 into engagement with the member 52 acting to couple the shaft to thepower. In order that this may be accomplished at will, I'-` employ aleverA 53 having one end engaging the member 51 and having its oppositeend' gagement, I employv a suitable stop element 55 adapted to be movedinto and out of the path of movement of a iange 51u carried by themember 51. rI`he element 55 preferably carries a rollerl at its upperend, which roller is adapted to engagesaid fiange 51a, a movement of theelement 55 in one direction serving to withdraw it out of the path ofthe flange 51a, thus permitting trie spring 54 to throw the clutch intoengagement. To provide this movement to the element 55, I employ a footlever 56; this lever is preferablyspring supported in order that whenthe lever or treadle 55 is released, it will return to normal position,and in such position will be located in the path of movement of a camlike portion of theflange 51L the action of which is to retract themember 51 and disengage the clutch, thus stopping the movement of theshaft-48.

From the above it will be understood that the valve structures,`beingcarried by the .tank bottom, are held against 'vertical movement, andsince the cups 89 provide the function of the `plunger 28 heretoforereferred to, it will be understood that in the apparatus 4hereindescribed, it is necessary that the containers be `moved toward and.

from the cups. rIhis action is provided bv the employment of a suitablecam 57, mounted on the'shaft 48, said cam being adapted to providemovement to a vertically reciprocating member 58, said member beingadapted to extend through the bed 81 and having its upper end providedwith a vmember 51 being adapted to move longituffl ing the containersthereon in proper `Vloca-- tion,-but I `prefer'lto employ the structureshown herein in which the upper endof the member 58 is'provided with aplate 59 .hav-

ing suitable guides 59a adapted to guide aA removable carrier 60, thelatter being-,preferably in the form of a flat plate 61 having astop61E-at its front and provided with a handle 61h. The plate is providedwithwa pair of dowelpins 62 and a supporting post 63, these pins andpost .being vadapted to support a plate 64 having -openings to receivethecontainers, the latter' preferably resting on the plate61. This.particular construction forms an'reflicient carrier in which the plate64; mayibelifted oiy of the pins and post andcarriedaway, thus enablingthe containers to be placed inposition at a point removed from theapparatus and then carried thereto andby positioning. the plate on thedowel pins sol asl to prevent the plate from twisting, they containerswill be properly positioned onthe plate 61.

I preferably form guide flanges-65 in advance of the plate 59 to receivethe carrier 60, the latter then being pushed on-to vthe plate 59 untilcontact is had therewith by the stop 61, this having the effect ofproperlypositioning the containers below the cups 36. As it is possiblethat paraflinmay drop onto the upper face of thev plate 59, i preferablyform the plate 61 with abeveled edge 61h, this edge beingadapted toscrape off such paraffin as may have passed ontothe plate 59 and carryit to the rear end of said plate 59 onto a chute from-where it passesinto a receptacle 66. p A

ln order to accommodate for various lengths of containers, I preferablymount them :aber 5S adjustably, as by the use of a threaded member 58aand awheel 5S, the rotation of which has the effect of raising orlowering the-plate 59 and thus adjusting the normal position of saidplate `59. The length of travel of the plate 59 being similar by the use`,of the cam-57 regardless of such adjustment,` it will be yunderstood'that such adjustment provides for meeting.

This

the valve structures. As the containers approach the =cups, the valvesare moved so as to bring thefopenings 37a into alinement with the'openings 36, thus permitting the measured paraflin to drop on to theexposed surface .of the food product which may be withinlthe container,the liquid forming a layer thereon. The vfurther movement of the shaftcauses the carrier to continue its upward'movement and at the same timereturns the valve to its normal position, thus taking away the openings37a from out of alinement with the openings 36a, to prevent a return ofthe paraffin thereinto.' This upward movement of the carrier then bringsthe upper surfaces of the paraffin layers into contact with the bottomsof the cups, and as the cups are of less diameter than the diameter ofthe glass or container., it will be readily r-understood that thefurther movement of the carrier -willcause pressure to be applied on theparaflin layer to displace a portion thereof and cause it to pass`around the side wall ofthe cup adjacent the bottom, the slightwamountofparaflin which may pass within the openings 36a being negligible. T hisdisplacement acts to provide the flange and at the same time causes theair bubbles to be broken, and the air expelled around the-side of theglass.- ln this connection the particular location of the cups becomesof importance, in that the heated paraflin will tendto keep the walls ofthe cups heated to a certain extent and consequently the parafiin layerwill not become hardened to an extent which would prevent the properoperation, with respect to the discharge of -air bubbles andtheformation of the flange and its close contact with the Vwalls of theglass. The continued movement of the sha-ft t6 then acts to return thecarrier to its normal inoperative position, whereupon the clutchmechanism is disengaged, after which the carrier may be removed at willand a new set of containers be placed in position to repeat theoperation.

As will be readily understood, the apparatus above described willprovide not only an efiicient packaging operation, but will also provideit with rapidity, all operations, with the exception of the positioningand removing of the carrier being automatic, so that a maximum output ofthe ap-y paratus is provided.

While l have shown and described a method for producing the packagereferred to, as well as an apparatus which will provide this result withefficiency, it will be readily understood that changes and modificationstherein may be required or desired to meet the erigencies of use, and Idesire to be understood as reserving the right to malte such changes andmodifications as may be necessary or desirable in this connection .in sofarl as the same may fall within the spirit and .scope of the inventionas eX- pressed in the accompanying claims. Also, in the use of termsthroughout the specification and claims I contemplate all equivalentsinineaning and in parts or materials. for instance, the term paraffintypifies and includes all sealing materialswhich may be used in asimilar manner.

Havingv thus described my invention,

what I claim as new is:
